Low-level object used to deserialize structs encoded with the Thrift compact protocol.

Implementation of this trait must provide the low-level functions read_byte, read_bytes, skip_bytes, and read_double. These primitives are used by the default functions provided here to perform deserialization.

Required Methods

fn read_byte(&mut self) -> Result<u8, ThriftProtocolError>

Read a single byte from the input.

fn read_bytes(&mut self) -> Result<&'a [u8], ThriftProtocolError>

Read a Thrift encoded binary from the input.

fn read_bytes_owned(&mut self) -> Result<Vec<u8>, ThriftProtocolError>

fn skip_bytes(&mut self, n: usize) -> Result<(), ThriftProtocolError>

Skip the next n bytes of input.

fn read_double(&mut self) -> Result<f64, ThriftProtocolError>

Read a Thrift double as f64.

Provided Methods

fn read_vlq(&mut self) -> Result<u64, ThriftProtocolError>

Read a ULEB128 encoded unsigned varint from the input.

fn read_zig_zag(&mut self) -> Result<i64, ThriftProtocolError>

Read a zig-zag encoded signed varint from the input.

fn read_list_begin(&mut self) -> Result<ListIdentifier, ThriftProtocolError>

Read the ListIdentifier for a Thrift encoded list.

fn read_full_field_id(&mut self) -> Result<i16, ThriftProtocolError>

fn read_field_begin( &mut self, last_field_id: i16, ) -> Result<FieldIdentifier, ThriftProtocolError>

Read the FieldIdentifier for a field in a Thrift encoded struct.

fn read_field_header(&mut self) -> Result<(u8, u8), ThriftProtocolError>

This is a specialized version of Self::read_field_begin, solely for use in parsing simple structs. This function assumes that the delta field will always be less than 0xf, fields will be in order, and no boolean fields will be read. This also skips validation of the field type.

Returns a tuple of (field_type, field_delta).

fn read_bool(&mut self) -> Result<bool, ThriftProtocolError>

Read a boolean list element. This should not be used for struct fields. For the latter, use the FieldIdentifier::bool_val field.

fn read_string(&mut self) -> Result<&'a str, ThriftProtocolError>

Read a Thrift binary as a UTF-8 encoded string.

fn read_i8(&mut self) -> Result<i8, ThriftProtocolError>

Read an i8.

fn read_i16(&mut self) -> Result<i16, ThriftProtocolError>

Read an i16.

fn read_i32(&mut self) -> Result<i32, ThriftProtocolError>

Read an i32.

fn read_i64(&mut self) -> Result<i64, ThriftProtocolError>

Read an i64.

fn skip_vlq(&mut self) -> Result<(), ThriftProtocolError>

Skip a ULEB128 encoded varint.

fn skip_binary(&mut self) -> Result<(), ThriftProtocolError>

Skip a thrift binary.

fn skip(&mut self, field_type: FieldType) -> Result<(), ThriftProtocolError>

Skip a field with type field_type recursively until the default maximum skip depth (currently 64) is reached.

fn skip_empty_struct(&mut self) -> Result<()>

Empty structs in unions consist of a single byte of 0 for the field stop record. This skips that byte without encuring the cost of processing the FieldIdentifier. Will return an error if the struct is not actually empty.

fn skip_till_depth( &mut self, field_type: FieldType, depth: i8, ) -> Result<(), ThriftProtocolError>

Skip a field with type field_type recursively up to depth levels.
